Disability care a 'catastrophic' failure

A "catastrophic" failure to protect people in Victorian disability care from assault and sexual predators is being investigated after families of victims say they were ignored.

Anne Mallia told the ABC's Four Corners program her son was groomed by a predator while he was in care with Autism Plus in Victoria, but her reports were ignored.

Maria Thomas also told the program her son was being targeted by the same man, but when Autism Plus urgently asked the Department of Health and Human Services to move the man, the request was rejected.

"(My son) was sexually assaulted in the shower while he's having a shower," Ms Thomas told the ABC.

Beverley Swann said her brother had been assaulted in a Lifestyle Solutions home and it was covered up.

Jean Hislop said her son was sexually assaulted by a staff member in a home run by the Victorian DHHS.

Autism Plus general manager of operations Edward Boghikian said he welcomed the government investigation into the claims, but was legally prevented from commenting on the case.
